Mercedes driver Lewis Hamilton of Britain leads the pack out of the 1st curve during the Formula One Grand Prix at the Barcelona Catalunya racetrack in Montmelo, Spain, Sunday, Aug. 16, 2020.
The talk before the race was whether Mercedes' tires would be vulnerable in the searing summer heat of Spain, after experiencing problems in the past two races at Silverstone.
After narrowly securing a record-extending 92nd career pole position Hamilton made a strong start on the long straight to the first corner.
Track temperatures on the circuit were around 50 degrees C (122 F) and Mercedes was concerned about catching too much sun.
These black overalls are hot, Bottas said during the race, throwing in an expletive for emphasis.
